United States Patent' fiice ABSTRACT OF THE DISCLOSURE A railway freight car lading band anchor assembly adapted to be manually movablefrom open to closed position by rotating the anchor structure about its axis which is generally parallel to and forms a part of the load supporting floor, or containing walls of the car.

Background of invention A lading band anchor of a railway freight car is adapted to secure fiat high tension bandswhich pass over or alternately around cargo placed upon the floor of the car. The distal ends of the bands pass around the anchor unit and return the band for securement to itself. Conventionally, ladinsg band anchors have been placed at locations to suit shipper. demands and are of a type wherein an open-ended housing is placed in an area having some form of anchor design associated therewith. These types of anchors, particularly when used in fiat car service have proven inadequate after a few years service due to corrosive action of the elements, as well as the fact that they present a problem of dirt and debris collection; ice and snow immobilizing the anchors effective use.

1 Summary of the invention The present invention relates to a high-tension lading band anchor for railway freight cars in which an anchor is rotatably mounted to adjacent car structures and the anchor is movable from closed to open position. It is the primary object of the present invention to provide an improved lading Iband anchor assembly mounted on the framing member of the car and wherein the action of the housing member when moved from open to closed position causes debris and foreign matter to dislodge itself and fall free of the anchor assembly.

Another object of the invention is to provide a round anchor seat, a portion of which forms the trunnion for the rotatable anchor assembly.

An additional object of the invention is to provide a lading band anchor housing which when not in use forms a part of the floor or restraining wall of the car, thereby closing the necessary opening to receive the lading bands.

A further object of the invention is to provide load bearing supports for the lading bearing housing when acting as a basic ear member such as the floor of a flat car.

A still further object of the invention is to position the housing load bearing supports so as to act as restraining walls against lateral displacement of the lading bands.

A feature of the invention is the elimination of fillets, either as by weldment, forging or casting, by securing the restraining Walls within the housing other than at the anchor seat.

With the foregoing its main objectives, other objects and advantages of the invention will appear hereinafter in the detailed description, be particularly pointed out in the appended claims and illustrated in the accompanying drawings, in which:

Detailed description Referring now in detail to the drawings, in which like reference characters designate like parts, the improved lading band anchor is designated as 12 when in open position and as 13 when in closed positionas applied to the floor 14 of a railway fiat car. As generally shown in FIGURE 6 is member 15 designating the floor of a railway box car, 16 the end of a box car and 17 the side of the car. I

Also generally shown as 18 is a possible location of the present invention adjacent the door area and 19, as closed, in the floor of the car with 20 designating the invention in open position.

In the end of the car is shown possible locations of the invention, 21 designating a closed anchor and 22 the anchor in open position.

It will be seen that the present anchor is adaptable to application to most any location on a railway car.

Associated car structure FLAT CAR The side sill of a flat car is shown as 23. Connected as by' riveting to side sill 23 is a crossbearer member 24. This crossbearer member 24 connects the sidesill 23 to a center sill (not shown) forming a portion of the backbone of a railway car underframe. Longitudinal stringer 25 rests on crossbearer 24 and supports the car floor generally shown as 14.

BOX CAR ANCHOR DETAILS The preferred embodiment of the invention consists of a base member and is shown as which is conveniently welded as at 47 to the crossbearer 24. To base member 30 is mounted upstanding bearing supports 31; bearings 32 are integral with supports 31 and are in axial alignment with the lading band anchor 33 which rotates within bearing members 22. Longitudinally spaced along anchor member 33 are housing supports 34 which act as restraining means against lateral displacement of the lading bands when the anchor is in use. When the anchor structure is in closed position and forming a portion of the floor, said housing supports act as load transmitting members. It will be noticed that supports 34 rest upon anchor 33 and have no fillets to overload the edges of the lading bands when they are drawn tightly about the anchor member 33.

Generally U-sh-aped housing member 36 is disposed about anchor member 33 and when in open position acts as a guide for the lading band when it is being placed around the anchor 33 for securement upon itself. The U-shaped housing member 36 is provided with end pieces the anchoring 35 having an opening wh'ch'surrounds anchor 33 and may be welded thereto, as-well astohousing'36. Disposed between upstanding members 31 and in the path of movement of U-shaped housing is angle stop 37 which acts as a limiting means for rotation of the anchor structure.

As shown in FIGURE 3, floor 14 is provided with an additional housing stop 39 which is placed in the path of movement 'of' housing 36. Passing through filler piece 38 is bolt 41 and nut 40 which secure stop 39 in place. Conveniently located and held in place by bolt 41 and nut 40 is a typical floor clip 50 which overlaps a portion of stringer 25 to hold the floor 14 in place. Filler 38 is provided with holes 42 so the head of the bolts 41 will be recessed below the top of the plane of the floor 14.

The outer edge of floor 14 is held in place by bolt 44 passing through side sill 23 and the bolt is held in place by washer 45 and nut 46.

The entire anchor structure is held in place and to the associated car structure as by welding 47. U-shaped housing member 36 is provided with drain holes 48, as well as a hole 49 to be used in lifting the housing member from closed position to open position.
